A Study of Initiation Timing of VTE Prevention After Colorectal Cancer Surgery
Recruiting now
Conditions studied: Colorectal Cancer
In brief
This project intends to conduct a single-center, prospective, observational cohort study to explore the impact of the timing of drug prophylaxis on the risk of postoperative bleeding and the preventive effect of VTE in the prevention and management of postoperative venous thromboembolism (VTE) after colorectal cancer (CRC) surgery in Chinese population, and to determine its application and promotion value. The research results of this project can provide useful reference for optimizing the prevention and management of VTE after CRC operation.

You may qualify if…
- ① Age > 18 years old;
- ② The patient was diagnosed with colorectal cancer, and the cTMN stage was cT1-2, N0 or cT3, N0 or any cT, N1-2; (3) The patient was diagnosed with colorectal cancer and was able to receive radical surgery (laparoscopic or open surgery). The expected operation time was >45 minutes, and the expected postoperative survival time was >6 months.

- known brain metastases, endocarditis, or history of heparin-induced thrombocytopenia;
- VTE occurred within 3 months before surgery;
- Use heparin or oral anticoagulant therapy within 5 days before surgery; Women who are pregnant or breastfeeding;
